Vintage Manual Sonometer
c. 1950s - 1960s; W.M. Welch Scientific Co. - Chicago
Hand crank sonometer, a musical and scientific laboratory instrument used to measure musical instrument string tension and wave mechanics. It works as such (from NYU):
The sonometer lays flat on a large surface. There is a meter stick attached for reference. Strum the strings freely or hold down the string in different positions like a capo, to achieve different notes. Strike the tuning fork and strum the strings, and turn the knob at the top of the sonometer to increase or decrease the tension, until the strings and the tuning fork hit the same note.
Exhibits moderate signs of wear consistent with age and is missing one scale.
51" W x 5.5" W x 5.5" H
